Emergency wash system

Abstract

An emergency wash system configured to dispense a fluid is disclosed. The system comprises a receptacle and a dispenser assembly disposed at least partially over the receptacle. The dispenser assembly comprises a fluid inlet portion configured to extend in a substantially horizontal direction when in use and configured to be in fluid communication with a fluid supply. The dispenser assembly also comprises a first outlet portion defining at least one first discharge opening, a second outlet portion defining at least one second discharge opening, a first fluid riser extending upwardly and outwardly from the inlet portion towards the at least one first discharge opening and a second fluid riser extending upwardly and outwardly from the inlet the first fluid riser towards the at least one second discharge opening on a side of the fluid inlet portion opposite the first fluid riser.

What is claimed is: 
     
       1. An emergency wash system configured to dispense a fluid from a fluid source, comprising:
 a basin; 
 a valve in communication with the fluid source; and 
 a fluid dispenser fluidly coupled to the valve and disposed at least partially over the basin, the fluid dispenser including:
 a fluid inlet portion fluidly coupled to the valve; 
 a first fluid outlet portion fluidly coupled to the fluid inlet portion; 
 a second fluid outlet portion fluidly coupled to the fluid inlet portion; and 
 a drainage aperture proximate to and spaced apart from a lower surface of the basin, the drainage aperture defined by the fluid inlet portion. 
 
 
     
     
       2. The emergency wash system of  claim 1 ,
 wherein the first fluid outlet portion extends upward and outward from the fluid inlet portion; 
 wherein the second fluid outlet portion extends upward and outward from the fluid inlet portion on a substantially opposite side of the fluid inlet portion relative to the first fluid outlet portion; and 
 wherein the drainage aperture is disposed between the first and second fluid outlet portions, and wherein the drainage aperture is disposed above a flood-level rim of the basin. 
 
     
     
       3. The emergency wash system of  claim 1 , wherein the drainage aperture utilizes gravity to drain at least a portion of fluid accumulated in the fluid inlet portion. 
     
     
       4. The emergency wash system of  claim 1 , further comprising a push plate rotatably coupled to the valve and configured to selectively open and close the valve to selectively permit fluid to flow to the fluid inlet portion. 
     
     
       5. The emergency wash system of  claim 4 , wherein the valve includes at least one stop member, the at least one stop member adapted to selectively engage with the push plate to control a range of rotation of the push plate relative to the valve. 
     
     
       6. The emergency wash system of  claim 4 , wherein the push plate includes indicia, the indicia providing a visual instruction to a user regarding how to activate the emergency wash system. 
     
     
       7. The emergency wash system of  claim 1 , further comprising a drain conduit fluidly coupled to the basin and extending in a substantially horizontal orientation away from the basin when the emergency wash system is in use, wherein the fluid inlet portion is oriented substantially parallel to the drain conduit and vertically above the drain conduit when the emergency wash system is in use. 
     
     
       8. An emergency wash system configured to dispense a fluid, the emergency wash system comprising:
 a sprayhead configured to selectively dispense the fluid, the sprayhead comprising:
 a fluid inlet portion; 
 a first fluid outlet portion extending from the fluid inlet portion, the first fluid outlet portion including a first discharge aperture for selectively providing fluid to a user; 
 a second fluid outlet portion extending from the fluid inlet portion on a side of the fluid inlet portion substantially opposite the first fluid outlet portion, the second outlet portion including a second discharge aperture for selectively providing fluid to the user; and 
 a drainage aperture defined by the fluid inlet portion, the drainage aperture spaced apart from a lower surface of a basin. 
 
 
     
     
       9. The emergency wash system of  claim 8 , wherein the fluid inlet portion includes an internal fluid passageway defining a longitudinal axis, the first fluid outlet portion and the second fluid outlet portion each extending upwardly and outwardly from the fluid inlet portion at an orientation that is substantially perpendicular to the longitudinal axis. 
     
     
       10. The emergency wash system of  claim 8 , wherein the first discharge aperture includes a plurality of first discharge openings, wherein the second discharge aperture includes a plurality of second discharge openings, and wherein each of the first and second discharge openings have a substantially circular cross section. 
     
     
       11. The emergency wash system of  claim 10 , wherein the plurality of first and second discharge openings are configured to provide the fluid to eyes of a user when the emergency wash system is in use. 
     
     
       12. The emergency wash system of  claim 8 , further comprising a filter configured to filter the fluid prior to the fluid reaching the first discharge aperture and the second discharge aperture. 
     
     
       13. The emergency wash system of  claim 8 , wherein the drainage aperture utilizes gravity to drain at least a portion of fluid accumulated in the fluid inlet portion. 
     
     
       14. An emergency wash system, comprising:
 a basin; and 
 a fluid dispenser disposed at least partially over the basin, the fluid dispenser including:
 a fluid inlet portion; 
 a fluid outlet portion in fluid communication with the fluid inlet portion and configured to direct fluid towards a user; and 
 a drainage aperture proximate to and spaced apart from a lower surface of the basin, the drainage aperture defined by the fluid inlet portion. 
 
 
     
     
       15. The emergency wash system of  claim 14 , wherein the drainage aperture utilizes gravity to drain at least a portion of fluid accumulated in the fluid inlet portion when the emergency wash system is not in use. 
     
     
       16. The emergency wash system of  claim 14 , further comprising a valve disposed upstream of the fluid inlet portion, the valve configured to selectively permit fluid to flow through the valve to the fluid inlet portion. 
     
     
       17. The emergency wash system of  claim 16 , further comprising a push plate rotatably coupled to the valve and adapted to selectively open and close the valve. 
     
     
       18. The emergency wash system of  claim 17 , wherein the valve includes at least one projection, the at least one projection adapted to control a range of rotation of the push plate relative to the valve. 
     
     
       19. The emergency wash system of  claim 14 , further comprising a filter configured to filter fluid prior to discharge of the fluid from the fluid outlet portion towards the user. 
     
     
       20. The emergency wash system of  claim 14 , further comprising a drain conduit fluidly coupled to the basin and extending in a substantially horizontal orientation away from the basin when the emergency wash system is in use, wherein the fluid inlet portion is oriented substantially parallel to the drain conduit and vertically above the drain conduit when the emergency wash system is in use.
